Receiver operating characteristics curves for the best performing model (validation set and applied to the testing set) for the purpose of predicting worsening of the radiological state. The chosen model was a support vector classifier with a sigmoid kernel and using 2 convolutional features. The testing AUC is up to 0.66, equivalent to the validation AUC of 0.67. The green shaded area corresponds to the 95% confidence interval for the testing AUC and ranges from 0.64 to 0.67 AUC.
